HID: microsoft: do not use compound literal - fix build
commit 6b90466cfec2a2fe027187d675d8d14217c12d82 upstream.
In patch "HID: microsoft: fix invalid rdesc for 3k kbd" I fixed
support for MS 3k keyboards. However the added check using memcmp and
a compound statement breaks build on architectures where memcmp is a
macro with parameters.
hid-microsoft.c:51:18: error: macro "memcmp" passed 6 arguments, but takes just 3
On x86_64, memcmp is a function, so I did not see the error.
